Enter your annual income and this rent affordability calculator shows how much rent fits at 25%, 30% and 35% of your gross pay, the most a landlord using the common 3x income test would approve, and a debt-adjusted figure that takes your existing monthly debt payments into account. It also adds your estimated utilities to the 30% figure, so you see the real monthly cost of the home — not just the rent on the listing. There is no sign-up and nothing to submit — the results update as you type.
Monthly debts means the minimum payments you already owe each month, such as a car payment, student loan or credit card minimums. Monthly gross is your annual income divided by 12, before tax.

Debt-adjusted guide
36% of gross minus your monthly debts: $1,450.00
If you already carry debt payments, this is often the more honest ceiling for rent.
Rent plus utilities at 30%
$1,500.00 rent plus $200.00 utilities: $1,700.00 a month
That total is the real monthly housing cost to test against your budget.
How the estimate works: your annual income is divided by 12 to get monthly gross income, then the percentage guides, the 3x test and the debt-adjusted figure are worked out from that monthly figure. The percentages are guides, not rules a landlord or lender has to follow, and they use gross income before tax — your take-home pay will be lower, so always test the final rent against the money that actually reaches your account.
How to use this calculator
- Enter your annual income before tax. If you have two incomes in the household, add them together.
- Add the monthly debt payments you already make — car, student loan, card minimums and similar.
- Add a realistic estimate for monthly utilities if they are not included in the rent.
- Compare the four figures: the 30% guide, the gentler 25%, the stretched 35% and the landlord 3x test.
- Check the debt-adjusted guide and the rent-plus-utilities total before you decide on a place.
The 30% rule, explained simply
The idea that housing should cost no more than about 30% of gross income has been used as a general US housing guideline for decades. It was never meant as a personal finance law — it is a quick way to flag when housing is likely to squeeze everything else. Treat it as the middle of three guides: 25% usually leaves comfortable room, 30% is the standard benchmark, and 35% can work for a while but leaves less slack for savings, debts and surprises.
Two things the rule does not do: it uses gross income, before tax, so it flatters what you can really pay; and it ignores debts you already have. A household with no debts and a household paying several hundred dollars a month in loan payments should not aim at the same rent on the same salary — which is exactly why the debt-adjusted figure exists on this page.
The landlord tests: 3x and 40x
Affordable for you and acceptable to a landlord are two different questions. Many landlords screen applicants with the 3x test — monthly gross income at least three times the rent — or the yearly version of the same idea, annual income of at least 40 times the monthly rent. Passing that test means an application is likely to be considered; it does not mean the rent leaves your budget in good shape. Run both checks: the landlord test to know what you can get, and the percentage and debt-adjusted guides to know what you should take.
A worked example
On a $60,000 salary, monthly gross income is $60,000 divided by 12, which is $5,000. The 30% rule gives $1,500 a month for rent. The 25% guide is $1,250 and the 35% guide is $1,750. The landlord 3x test gives $5,000 divided by 3, or $1,666.67. With $350 a month in existing debt payments, the debt-adjusted guide is 36% of gross ($1,800) minus $350, which is $1,450 — a little below the headline 30% figure, and the more honest ceiling for that household. Add $200 of utilities and the $1,500 rent really costs $1,700 a month all-in.
Before you sign a lease
- Ask which utilities are included and which are yours — it can change the real cost by a lot.
- Budget for the move itself: deposit, first month and moving costs land at the same time.
- Test the rent against take-home pay, not just gross pay, before you sign.
- Keep an emergency cushion — a rent you can only just afford leaves nothing for a bad month.
If you are renewing rather than moving, our guide on how to negotiate your rent before signing a renewal walks through the conversation, and the guide to saving for moving costs covers the upfront money a move really needs.

Frequently Asked Questions
What percentage of income should go to rent?+
The long-standing guide is 30% of your gross monthly income — income before tax. It is a guide, not a law. On a lower income, or in an expensive city, even 30% can feel tight because the amount left over has to cover everything else. That is why this calculator also shows 25% and 35%, plus a debt-adjusted figure, so you can judge the rent against your whole budget rather than one percentage alone.
What is the 3x rule for rent?+
Many landlords ask for monthly gross income of at least three times the rent. A $1,500 apartment would need about $4,500 a month in gross income. Turned around, your monthly gross divided by 3 is roughly the most rent that kind of landlord test would approve — which works out to about 33.3% of gross income. It is a screening rule landlords use, not a promise that the rent will feel comfortable.
Do landlords use gross or net income?+
Landlords usually use gross income — the figure before tax and deductions — because it is the number on an offer letter or pay stub and it is easy to check. Your own budget should use net income, the money that actually arrives in your account. A rent that passes a landlord test on gross income can still be too much once tax, debt payments and everyday costs come out of your take-home pay.
Should utilities count towards the rent percentage?+
For your own planning, yes. Rent is only part of the cost of a home — electricity, gas, water, internet and similar bills arrive every month too. This calculator shows the 30% rent figure plus your estimated utilities as one total, so you can see the real monthly housing cost before you sign, rather than discovering it in the first full month of bills.
What if 30% is impossible in my city?+
Then the percentage is a starting point, not a verdict. Use the debt-adjusted figure on this page, which takes your existing debt payments into account, and look hard at the rest of the budget: a higher rent share usually means cutting transport, sharing with housemates, or choosing a longer commute. Our budgeting guides can help you test what a higher rent would mean for the rest of your month before you commit.
